Ordered one on Amazon myself, £105 including delivery as it was coming in from Italy (Brixiamoto). Delivery was supposed to be early June, however it turned up yesterday afternoon - both parts in the box too!
I have put the base screen on the topmost selection and have the adjustable screen all the way down - I'm 5'11" by the way, I find this gives me vision over the top of the screen by a couple of inches and means that if I take out the adjustable screen for cleaning, I know it slots down as far as it will go, no need to mark the spot that works for me!
I'm not the biggest fan of the look of the screen, but for effectiveness it is superb, on a motorway run I had no wind noise and the buffeting has almost completely vanished.
